Today, in 2024 and beyond, the Key2 faces a harsh reality: It never received Android 9, 10, 11, or 12. Security patches have stopped. Apps are slowly dropping support for older Android versions.

In the annals of mobile history, the BlackBerry Key2 (released in 2018) occupies a bittersweet throne. It was the last true BlackBerry—the final physical QWERTY phone designed by the now-defunct BlackBerry Mobile (under TCL licensing). For keyboard junkies, it was a dream machine. For the rest of the world, it was a bizarre relic.

Most Android phones allow you to unlock the bootloader ( fastboot oem unlock ). The BlackBerry Key2 does not. BlackBerry (TCL) implemented a security architecture so strict that the bootloader is factory-locked to prevent tampering. Out of the box, fastboot flashing unlock returns a permanent "denied." For three years, the Key2 was a fortress. Then, in late 2021, a Chinese developer known as Asher (aka @sldhmnb on Telegram) discovered a low-level exploit using Qualcomm's EDL (Emergency Download Mode) and a firehose programmer.
